Supporting a Circular Economy

Caterpillar products are built to be rebuilt. They are designed to withstand heavy-duty operating conditions and to be restored and used for multiple lifecycles, reducing the need for raw materials and associated GHG emissions.

Remanufactured parts, commonly used in rebuilds, provide customers with quality products that help lower the total cost of ownership. Remanufacturing also helps Caterpillar contribute to the circular economy. Together, these benefits are why we have a goal to increase sales and revenues from remanufacturing offerings by 25% by 2030.

Remanufacturing means to return end-of-life product to original quality and performance specifications using a combination of salvaged and new parts in a manufacturing environment. Remanufacturing also helps keep high-value raw materials, such as iron, in productive use and helps extend the value created through the use of important resources like energy and metals consumed in a component’s original manufacturing process.

Increase sales and revenues from remanufacturing offerings1 by 25% from 2018 to 2030.

31%

increase in sales and revenues from remanufacturing offerings from 2018

Progress includes:

  • 147 million pounds of material taken back for remanufacturing through Cat Reman.2
  • Cat Reman introduced 29% more remanufacturing offerings from 2018 to 2023 to support sustainability and total cost of ownership initiatives.2
  • Remanufacturing produces 65-87% less GHG process emissions compared to manufacturing new parts.3
  • Cat Reman product line meets the needs of the industries served by Caterpillar, including construction, mining, energy and transportation, as well as on-highway truck engines. We have parts for agriculture, demolition and scrap, forestry, railway power and more.

Putting Circularity to Work


Remanufacturing
For many products and components, the remanufacturing process begins when we design them intentionally with multiple lifecycles in mind. The quality and durability required to withstand heavy-duty operating conditions also translate into the potential for more than one product life.

The remanufacturing process uses the proprietary know-how of the original manufacturer. The result is a like-new component created using fewer new materials because we use the existing core.

Here are steps within our remanufacturing process:

Product and Parts Return

When eligible parts or components reach the end of one life, they may be returned to the respective Cat dealer or subsidiary, Solar Turbines or Progress Rail.

Remanufacturing & Assembly

Repair options include reassembly to original Caterpillar performance and quality specifications. For Cat Reman, the advanced remanufacturing processes and quality controls provide like-new performance, coupled with a same-as-new warranty.

Dissassembly & Cleaning

We inspect all products and components before disassembling them down to their individual parts. A multi-part cleaning process ensures the removal of microscopic debris.

Return to Customer Use

Rebuilt equipment with remanufactured components is provided to our customers, extending the life of their assets.

Rebuild Programs
 

Cat Certified Rebuild programs increase equipment lifespan by providing customers with product updates at a fraction of the cost of buying a new machine, extending the life of materials. A complete Cat Certified Rebuild includes more than 350 tests and inspections, automatic replacement or reconditioning of approximately 7,000 parts, and a like-new machine warranty. Trained dealer service professionals perform rebuild work using genuine parts while incorporating the latest engineering updates. Caterpillar provides information, data, training and service tools to help dealers decide which parts to reuse to achieve the expected longevity of rebuilt components.

Benefits of a Cat Certified Rebuild include:

  • Opportunity for product enhancements introduced after the equipment was first manufactured.
  • Upgrade optional features and technologies to current standards, which may reduce costs, boost productivity, and enhance efficiency, all at a lower cost compared to new.
  • Same-as-new support and services from the dealer and financing options through Cat Financial.

Since 1985, Cat dealers have completed more than 50,000 Cat Certified Rebuilds on machines, powertrains and components.
